If the ribbon is to be rejuvenated, the absorbent material 12 and 62 within the containers 1 and 51 is saturatedv with an ink solvent, which is introduced through the filling openingsv 11 and 61 lin the cover plates 8 and 58. The containers are then moved away from each `other by pressing .down the `thumb piece29, which causes the cam 34 toengage the cam follower 35 and move the slide 16, against theforce of spring 23 carrying'.

the container 51, away from the containerl. The,

ribbon is then inserted between thel containers;

and the thumb piece 29 is released-,whereupon the compression spring 32- returns the plunger-28 toi its initial position. The ribbon is thenpassed between felt faces 2.1 and 'lzan'd is rejuvenated -intodirect parallel IJhysical*contact with the felt faces. 1 i i I'he device is used to re-ink ribbon inasimilar manner,` with the exception thatf-the absorbent material is saturated with ink instead'of a solvent; The external surface ofthe stem27 below the y finger piece 33.1is"knurled,at37, Fig. 1, to prevent the device from turning, in use, .between'the- 4 Y i ingsaid supports for urging the containers to fingers. w

slide 41 for'urging the ribbon'finto direct physi-V cal contact with theabsorbent materi`a142 as fthe 'ribbon'.is moved therebetween. In` thisca'se,nthe

slide 41, is Vurged inwardly by the; tensionsprlng 43 having one y'end connectedtoa hook 44' -provided on. tl1'e' slide and thev otherend connected to the closureplate 45. The slider is provided' with a slot 46 which coactslwith the screw .47 to slidably supportthe slide. on the bottom ofzthe` container 48.' i

Our 'improved device is simple and compact in construction, yet highly effective forY the purpose intended. ,With it, all vkinds o'f-transfer ribbons, films, and `the like may be quickly cleaned, ,and rejuvenatedor re-inked. .:v l In our device, the felt facesare made` to contact-with and -bear evenly -onlboth sides-lof the ribbon. This yuniform pressure on both sides of thek ribbon prevents it from working outofthe" device as in prior devices of this character, This improved feature is brought about bysupporting the containers, sov that the feltfaces are maintained inparallel `relationthroughout the: rela.- i `tive, movementbetween the containers.; 'I'he uniform pressureon the ribbon, provided by the device, is not aieeted by wear.Y

'Where the device Vis used for cleaning moving picture films and the like, the absorbent material may be saturated with an oil solvent such as Car-V fingers, leaving the thumb free tofdepress the# plungen which forces the pressuremember out at-right angles to the axis lof the plunger, enabling the operator to convenientlyhold the same in this position, while positioning the `ribbon vbetween, the pnesediacss. .i
